Hi, Leonard
This is the problem!
One of the main problem.
The message in Italian is mine.
I show the message when the script return null.
In this case, the script abort in this section:
var buttonSave = this.getField("Salva");
if (buttonSave == null) {
app.alert({cMsg: "Attenzione probabile problema con questo
reader, non è stato in grado di leggere il campo 'Salva'",cTitle:
"Acrobat reader Problem..."});
}
else {
buttonSave.value="";
}
I try to read the button named "Salva" but this return "null".
I think because that object is out of the visible part of the screen!
This happen when we open this file with Reader 8.0, if I try to
open with other reader, sometimes work, and sometimes work in the
same 8.0. It’s random?
In this case, with reader 8.0, if enable the console I see this
message:
NotAllowedError: Security settings prevent access to this property
method.
Filed.borderColor:249:Page undefined:Open
Thanks,
Aristide

I opened this document and received two alerts (in Italian) which I
suspect are yours and what I should be seeing. Yes?
So what is the problem? When it "doesn't work" - what happens
instead?

Hi Alexis, thanks for you quick response.
Yesterday I have upgrade the library to the version 1.4 (by
lowagie.com)
But nothing change. Sometimes the javascript fails when the
document is
open, in the version 8.0 but regularly fails in 7.0 not in 6.0.
We have only use simple script that normally you can add with Acrobat
Professional. This script run when the document is open.
My suppose : we have this problem only because we are running into the
browser.
But I have hear one interview release from Bruno Lowagie on
JavaPolis and we
have produced an application like the application written for the
ghent
university.
We use PDF with AcroForm, fill that from servlet, send to the
browser, plug
in open the document, start with javascript than interact before
the user
fill some fields and then submit the data to the same servlet.
I think is a problem of openpage() action. Because I have insert in
the
template PDF a start function called ?init();?, and with iText put the
script with
writer.addJavaScript(?function init() { ?. }?);
we have resolved with workaround but i don?t understand this bug!
I attach a simple test page, generate from my servlet, with the
workaround.
Thanks.
Aristide

Oggetto: Javascript
We have use PDF for an application input, generating from a
servlet, this
application is used in 50.000 clients.
With the iText library we put in FIELDS of a different template
document
(designed with Acrobat Professional 6.0) the correct value, this
value is
readed from DB.
For the presentation, with javascript we force different command
for modify
the background color, the visibility / enable / disable of fields
and button
than send this FIELDS to the same SERVLET, like a HTML FORM
application.
This work fine width ?Acrobat professional 5/6? and with ?Acrobat
Reader
versions 6?, but with some other release we have a strange behaviors.
like this, look this javascriptscript :
var objText=app.getField(?textFieldName?);
this start at the open document, I have put the commands using the
writer.addJavaScript(??the script??);
that script return the real object only if the object is really
showed in
the visible scroll region of the reader, this is contained in a
browser
window.
Return null, if this object is outside the visible scroll region.
This behaviour is normal with acrobat reader 7.0, & incredible
also, 8.0.
I have find a workaround : copy the fields in the upper region of the
document and reduce the size to 0,0 & visibility:true;
In this case the script run in the correct way, but I don?t
understand why
this don?t work naturally?
The same problem appears when use the combo object, check option,
radio
option, set a value from the iText api (from.setField(?)), but in
this case,
in the showed window, the combo is positioned on the default value,
but
internally the value is correct!
We use the iText version r1.01;p126
Do you any idea?
Thanks a lot, for all.
